The start of the "Pueblo Blancos Route", the city of Olvera is located in the province of Cadiz, in the northwest of the Serranía Gaditana area, near the borders of the provinces of Seville and Malaga, on 36º56' north and 0º16' west, at a height of 643 meters above sea level and has a land surface of 194 km².The distance between the capital and the Olvera is 139 km,. The number of inhabitants, according to the INE of 2005, is 8,585, although the number of "Olvereños" is possibly greater as migration to the coast (specifically to the Costa de la Luz) in search of employment where individuals decided to change their address to their place of work.The hills surrounding Olvera are full of olive tree plantations that provide the best extraction of olive oils in Andalusia. In fact, in the last years it has received the award of the "Denominación de Origen de la Sierra de Cádiz", which is a standard that is recognised by participants; nearby towns like Setenil, Algonodales, Alcala del Valle, Torre Al-haquime etc. While olive groves are of great importance to the economy, the largest economic source of this colourful town is the "cooperative" and the prize "Arco Iris" of 1989 was won due to the town having the greatest number of cooperatives per inhabitant.Of great interest within the municipality is a large colony of Andalusian leonado Vultures to be found within the natural reserve of the "Peñon de Zaframagón", a huge rock outcrop that is located 14 km to the northwest of the town centre.
